3Q 12, 13, and 14. A tank, indicated generally bythe Vnumeral 15, isprovided having av well 16 and a longitudinallyv extending portion 17,as shown clearly in Figure 1. The tank is provided with a perimetricalange 13 having a depending portion V'19. As shown in Figure 3, theflange 18 on Y the right hand side of the tank is at an elevation lowerthanthe portion on the left hand side of the tank, While theend portionsof the ange at an angle as indicated by dotted lines Vin vsaid Figure 1.The flange 18 with the depending .por` tion 19 serves to entrap productsof vcombustion and unconsumed gas and to conduct the same I .around thetank to the pipe 20 which is provided with an enlargement 21, by meansof which such gases are conducted from the proof box. The diameter ofthe enlargement 21` is suniciently large to catch the gases escapingfrom the opening 18a during the slight to and fro movement of the tankwhich takes place during the use'of the apparatus. A e The arm 12 ofthebase 10 maybe' provided with a vgroove 12a'in its'uppersurface,asshownwin,`

If the arm 26 is over the full steam legend,

the operator will know that 'the burner 25 is ap-f proximately intheposition shown in Figure 2,

while if the arm` is over thehalf steam? legendhe will known that theburner is slightly removed Vfromlbeneath the'tank although in-sufellposii`- tion-that a small quantity of steam will be;pro'

duced. When the arm 26`is'over the dry neat legend the burner 25 isentirely removed from be# neath .the tank and serves to provide dryheatlfor the proof box,1but1,not steam: As is shown-in FigureS, a baffle 43vserves to protect the tank 1'5 From theabove it 'will be seenthatV avery comlpact humidifier has been provided'in which'a float controlledvalve vhas been eliminated, which 'in the past has beenv thel source ofconsiderable dif` culty in that waterdeposited material frequente lycaused the valves toclog :and the tanks thus to burnout. 'It will also;be apparent that vthe tank 15 can bei removed for cleaning or replace` Yment'without the use of 'anytools since it merely rests upon the arm 12,being limited in its rocking movements by they stop 22 andthe valve 33.
